Abstract: <P>PROBLEM TO BE SOLVED: To provide a semiconductor device having a threshold voltage not lower than 0 V.   <P>SOLUTION: A manufacturing method of the semiconductor device includes a process for growing the crystal of a GaN buffer layer 14 on a sapphire (0001) substrate 11 with a vertical axis relative to the principal surface of the substrate as a c-axis to form a GaN(1-101) facet plane 14a, a process for forming an electron-transit layer 15 and a barrier layer 16 on a facet plane 14a, a process for forming high-impurity-concentration n-type regions 20, 20 in source/drain- electrode forming regions, and a process for forming source, drain, and base electrodes 17, 19 and 18 on the barrier layer 16. In this case, the plane orientation of the interface between the electron-transit and barrier layers 15, 16 is directed to a (1-101) plane. Therefore, polarized charge generated at the interface is made small and the concentration of two-dimensional electron gas produced at the interface is made small, so that the threshold voltage of the semiconductor device is not lower than 0 V. Thereby, a heterojunction field effect transistor capable of being operated without using a negative voltage can be obtained.  <P>COPYRIGHT: (C)2004,JPO
